Clean room workshop sterilization leak detection
Clean room sterilization equipment generally includes moist heat steam sterilization and water bath sterilization. Small volume injections mainly use moist heat sterilization. Of course, the process parameters can be determined according to the nature of the product, but the verification requirements must be followed. Carry out verification to ensure the quality of the product; the working procedure of the autoclave leak detection cabinet includes three processes: sterilization, leak detection and flushing. It is composed of meter, safety valve, water spray pipe, etc. When working, put the items in place as required and push in, close the box door, then open the steam valve first, let the steam pass into the interlayer for heating for about 10 minutes, and the interlayer pressure reaches about 0.2MPa. When the internal temperature reaches the controlled temperature, start timing. When the sterilization time is up, first close the steam valve, and then open the exhaust valve to discharge the steam in the box, and the sterilization is over; in order to ensure the sterilization effect and ensure the removal of cold spots, in Electronic technology and vacuum technology are added to the autoclave sterilization leak detection cabinet. Through electronic control, the steam can sterilize the product according to the specified pressure and time. Air to ensure the elimination of cold spots, thereby ensuring the quality of the product.
Injection clarity inspection is the key to ensure the quality of injections. There are usually two methods: artificial light inspection, and ampoule foreign body photoelectric automatic inspection instrument. Manual light inspection is mainly through visual inspection. Generally, fluorescent light is used as the light source during inspection, and the baffle is used to prevent direct light from entering the eyes. The background should be black or white, and the detection purpose is achieved by the movement of particles in the liquid medicine after the ampoule to be tested is shaken. , the method is to place the ampoule to be tested under the inspection lamp at a distance of 200mm from the light source and turn it gently, and visually check whether there are foreign particles in the liquid. The principle of the photoelectric automatic inspection instrument for ampoule foreign matter is to use the photoelectric system to collect the signal of the size and number of particles in the moving image, and to eliminate the static interference, and then through the circuit processing, the display results of the size and quantity of the insoluble matter can be directly obtained, and then through the mechanical action. Immediately remove the unqualified ampoules; at the moment when the ampoules are stopped, the ampoules are illuminated with a beam of light, and the scattered light or projection will be generated under the beam irradiation, and the images of the ampoule and the liquid will appear on the fluorescent bottle behind. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and sterile workshops.
The injection ampoules that have been sterilized and passed the quality inspection can enter the ampoules packaging production line, where the ampoule printing, boxing, instruction manuals, labeling and other operations are completed. The cartoning and capping machine is made up of four single machines linked together. The ampoule printing machine is mainly composed of carton conveyor belt, printing wheel, bottle feeding wheel, inking wheel, ink equalizing wheel and other components; the ampoule falls from the sliding track of the ampoule plate and directly falls onto the bottle holder plate with sponge pads , the bottle pushing plate sends the bottle holding plate and the ampoule to the under the printing wheel synchronously, the rotating printing wheel also drags the ampoule to roll in reverse while pressing the ampoule, and the ink writing is printed on the ampoule. The disadvantage of ink printing is that it is easy to produce sticky characters, and the quality of the ink is very important; since the rolling contact between the ampoule and the printing wheel only accounts for 1/3 of its circumference, all characters must be placed within the scope of less than 1/3 of the ampoule circumference. .
